PDF documents (images below) about the C7 Corvette have turned up on GM's media site and if the specs on the the C7 coupe sheet is final (which they appear to be since they no longer have 'est.' [estimated] next to the numbers), then we now know that the 2014 Corvette has official HP and torque figures of 455HP and 460 LB-FT.

Compare these final figures to the specs for the C7 Convertible, which still has the estimated (est.) figures on its sheet.

If you remember, the estimated figures released at the C7 launch was 450 HP / 450 LB-FT, so the final numbers are a nice little bump from the original 'estimates.'

it's today's TR6060 but with an additional very tall overdrive (0.46). Otherwise, ratios look identical to the current C6 (Z51 package = current Gran Sport gearing). The latest gearboxes are pretty damn good on the C6 (last one I've driven was a 2011) so if it's basically the same Tremec unit then I personally won't complain much. The active rev-matching feature is something I'm looking forward to seeing in real life.
